SYNOPSIS

DESCRIPTION

The makedbm utility takes the infile and converts it to a pair of files in ndbm format (see ndbm(3C)), namely outfile.pag and outfile.dir. Each line of the input file is converted to a single dbm record. All characters up to the first TAB
or SPACE form the key, and the rest of the line is the data. If a line ends with `\' (backslash), the data for that record is continued on to the next line. makedbm does not treat `#' (pound-sign) as a special character.

Because makedbm is mainly used in generating dbm files for the NIS name service, it generates a special entry with the key yp_last_modified, which is the date of infile
(or the current time, if infile is `-'). The entries that have keys with the prefix yp_ are interpreted by NIS server utilities.

OPTIONS

The following options are supported:

-b
Insert the YP_INTERDOMAIN into the output. This key causes ypserv(1M) to use DNS for host name and address lookups for hosts not found in the maps.

-d yp_domain_name
Create a special entry with the key yp_domain_name.

-Dnumber_of delimiters
Specify number_of_delimiters to skip before forming the key.

-E
Delimiters are escaped.

-i yp_input_file
Create a special entry with the key yp_input_file.

-l
Lower case. Convert the keys of the given map to lower case, so that, for example, host name matches succeed independent of upper or lower case distinctions.

-m yp_master_name
Create a special entry with the key yp_master_name. If no master host name is specified, yp_master_name is set to the local host name.

-o yp_output_name
Create a special entry with the key yp_output_name.

-s
Secure map. Accept connections from secure NIS networks only.

-Sdelimiter
Specify the delimiter to use instead of the default delimiter for forming the key.

-u dbmfilename
Undo a dbm file. Prints out the file in text format, one entry per line, with a single space separating keys from values.

OPERANDS

The following operands are supported:

infile
Input file for makedbm. If infile is `-' (dash), the standard input is read.

outfile
One of two output files in ndbm format: outfile.pag and outfile.dir.
